Trial Outcomes & Findings for A Study of Oral Valcyte (Valganciclovir) in Pediatric Kidney Transplant Recipients (NCT NCT01376804)

NCT ID: NCT01376804

Last Updated: 2017-07-11

Results Overview

An AE was any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not considered related to the medicinal (investigational) product. Pre-existing conditions which worsen during a study were reported as AEs. A SAE was any experience that: resulted in death, was life-threatening, required in-patient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect or was medically significant.

PRIMARY outcome

Timeframe: 52 weeks

Population: Safety Population included all enrolled patients who received at least one dose of study medication and had at least one post-baseline assessment of safety.

An AE was any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not considered related to the medicinal (investigational) product. Pre-existing conditions which worsen during a study were reported as AEs. A SAE was any experience that: resulted in death, was life-threatening, required in-patient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect or was medically significant.

SECONDARY outcome

Timeframe: 52 weeks

Population: Intent-to-treat (ITT) population included all enrolled patients who had taken at least one dose of study medication.

A polymerase chain reaction (PCR) based assay or antigenaemia assay was used for the qualitative assessment of CMV viremia (presence of CMV in the blood) by each study center as part of the clinical assessment required for diagnosis of CMV infection.

SECONDARY outcome

Timeframe: 52 weeks

Population: Intent-to-treat (ITT) population included all enrolled patients who had taken at least one dose of study medication.

A polymerase chain reaction (PCR) based assay or antigenaemia assay was used for the qualitative assessment of CMV viremia by each study center as part of the clinical assessment required for diagnosis of CMV infection. CMV disease included CMV syndrome or tissue invasive CMV. CMV syndrome required fever ≥ 38 degrees Celsius, severe malaise, leukopenia on 2 separate measurements, atypical lymphocytosis ≥ 5%, thrombocytopenia, elevation of hepatic transaminases and presence of CMV in blood. Tissue Invasive CMV required evidence of localized CMV infection in a biopsy or other appropriate symptom and relevant symptoms or signs of organ dysfunction.

SECONDARY outcome

Timeframe: 52 weeks

Population: ITT population included all enrolled patients who had taken at least one dose of study medication.

Blood samples were sent to a central lab for the quantitative assessment of CMV viral load (amount of CMV in the blood) by an FDA-approved molecular-based assay. The number of participants in each category is reported in copies/milliliter (CP/mL). CMV DNA is detected in all categories \< 150 CP/mL and above.
